A week before the FIFA presidential election, Concacaf general secretary Chuck Blazer has informed the body's Ethics Committee that during a meeting in the Bahamas two weeks ago violations may have been committed by four officials, including presidential candidate Mohamed Bin Hammam and Concacaf president Jack Warner.

Bin Hammam and Warner will be questioned by the committee on Sunday regarding possible bribes for votes in the election. Caribbean Football Union officials Debbie Minguell and Jason Sylvester have also been charged.

A FIFA statement read, "On 24 May, 2011, Fifa executive committee member and Concacaf general secretary Chuck Blazer reported to Fifa secretary general Jerome Valcke possible violations of the Fifa code of ethics allegedly committed by officials. In particular, the report referred to a special meeting of the Caribbean Football Union, apparently organised jointly by Fifa vice-president Jack A. Warner and Fifa executive committee member Mohamed Bin Hammam, which took place on 10-11 May 2011. This meeting was linked to the upcoming Fifa presidential election."

Earlier this month, FIFA launched an investigation regarding bribes solicited by FIFA Executive Committee members during the final World Cup bidding process in December. Warner is one of the committee members under investigation in that inquiry, which stemmed in part from an investigative report by the Sunday Times newspaper that cited payments to Executive Committee members in exchange for World Cup votes.
